l atentecl Nov. 2 9, 19 32 UNITED STATES PATENT orrice SHIN-ICHI OKI, OF SENJ'U MAGHI, MINAMI ADAGHI GUN, TOKYO FU, All-AN, ASSIGNOIB TO. SHINZABURO SHIBUYA 0F TOKYO, JAPAN ANILA HEMP IBEATER Application filed September 18, 1931, Serial No. 563,523, and in Japan November 12, 1930.

The present invention relates to a manila hemp beater comprising two groups of fluted rolls, the main beater and an auxiliary beater each arranged behind the corresponding groups of said fluted rolls, an obstruction roller cooperating with the main beater blade and an obstruction member slidably mounted upon the frame, the obstruction member having the upper and lower covers connected thereto so as to be exposed to or hidden from the co-operative relation with the auxiliary beater blade by said covers.

The object of this invention is to obtain a manila hemp beater which can operate alwaysin the same direction with high elfi ciency while it is continuously fed.

Referring to the accompanying drawing, Fig. 1 shows a side elevation of the manila hemp beater according to this invention; Fig. 2, an end elevation of the same and Fig 3, a section showing the coverplates which cover an auxiliary beater wheel and an obstruction element coacting therewith to constitute a passage for permitting hemp to pass freely between said cover plates. 1

In the drawing, 1, 2 and 3, 4 are pairs of feed rolls arranged at the front end of the machine; and 5, 6 and 7, 8, pairs of feed rolls arranged at the rear part of the machine, each pair of feed rolls consisting of two fluted rolls meshing with each other. The main beating wheel 9 and an auxiliary beating wheel 10 are rotatably mounted upon the machine, and alternately disposed with reference to the feed rolls 3 and 5 respectively in such a manner as to be rotated in the opposite direction to each other by means of driving belts 11 and 12 respectively. These beating wheels consist of cylindrical drums 13 having a number of blades 14 fixed around them in parallel with suitable space.

An obstruction roller 15 is mounted on the frame of the machine below the main heating wheel 9 so as to be able to coact with said blades and is adjusted by a handle 16. The hemp fibre beaten between the main beating wheel and the obstruction roll is delivered outside through a guide plate 17 7 To the shaft of the auxiliary beating wheel 10 are secured a driving pulley 18 and a bevel gear 19 with which a bevel gear 21 fixed to the shaft 20 mounted on one side of the machine meshes. To said shaft 20 are secured four helical gears 22, which gear with the helical gears 24 fixed to one end of the shafts 23 of the fluted rollsl, 3, 5 and 7, so that said fluted rolls may be rotated. The above roll shafts 23 are each provided at their other end with a spur gear 25 which meshes with the spur wheel 27 fixed to the same end of the corresponding lower roll shaft 26. Consequently, with the rotation of the auxiliary beating wheel 10 the shaft 20 also rotates and each upper roll is rotated by the gearing of the helical gears 23 and 24. Further, by the gearing of the spur gears 25 and 27 the lower rolls are rotated in the opposite direction to the upper rolls to feed hemp to the machine from the front to the rear.

On the shaft of the auxiliary beating wheel 10 is loosely mounted a supporting arm 28, to the free end of which an arc-shaped cover plate 29 is attached, said supporting arm being connected to a sliding obstruction element 31 by means of a link 30. The obstruct-ion element 31 guided to the guide groove 33 of the frame by the projection 32 at its side, can move up and down. Its lower part is connected to an eccentric strap loosely mounted on an eccentric sheave 34 fixed to the shaft 36 supported in a certain position on the frame. To, the shaft 36 are fixed an arm 38 supporting the lower cover plate 37, and a V crank 39, the free end of which is connected by a link 42 to one end of the lever 41 supported by a column 40, The other end of lever 41' is connected by a link 45 to a bell crank lever 44 pivoted to the frame at'43. 46 is a counter-balance secured to the handle lever 44. r

In Figure 1, the cover plates 29 and 37 open as shown by a full line to expose the beater blade 14 and obstruction element 31 to a condition to make them coact. In this statethe hemp delivered from the front to the rear of the machine undergoes beating action. When in Figure 1 the handle 44 is and moves the obstruction element 31 down to an inoperative position through the strap 35, at the same time swinging the lower cover plate 37 upward to cover said obstruction element and also swinging the upper cover plate 29 downward through the link 30 to cover the blade. In this case, the upper and lower cover plates form a guide passage between them so as to allow hemp to passthrough freely, as shown in Figure 3.

According to the present invention, if the auxiliary beater 10 and coacting obstruction element 31 are firstly covered with the cover plates 29 and 37 and hemp is fed through the feedrolls 1, 2, and 3, 4:, the hemp is delivered between the main beater-9 and obstruction roller 15 through the guide passage between said cover plates and then through the feed rolls 5, 6 and 7, 8, to be beaten by said heater and then delivered outside. If the handle 44 is moved to the position shown in Figure 1 when the hemp fibre has passed between the front drawing rolls, the cover plates 29 and 37 are opened as shown by a 5? gxfull line and cause the blade 14 and obstruction element 31 to be protruded to a coacting position, so that the blade 14 beats the fibre in the opposite direction to the travel of the hemp. Thus, the auxiliary beater beats the ;)1631 end of the hemp of a certain length completely. Without the auxiliary beater, the hemp which has passed between the rear feed rolls 7 and 8 would be unable to receive beating action perfectly from the main beater 35; and would have to be beaten repeatedly by reversing its position.

According to this invention, as the rear end of hemp material unable to be beaten sufficiently with the main beater is acted upon by the auxiliary beater prior to its passage to the main beater, there is the advantage of always passing the material through the machine continuously from one end and extracting the fibre very efliciently during gthat time.

I claim:

A manila hemp beater comprising two groups of fluted rolls, a main beater and an auxiliary beater each arranged behind the gcorresponding group of said fluted rolls, an obstruction roller cooperating with the main beater blade, a frame, an obstruction member slidably mounted in the frame, upper and lower cover members connected by link mechanism to said slidable obstruction member and means for actuating said slidableobstructi on member to move the cover members into a position either to shield the material passing through the machine from the action of the auxiliary beater or to expose the material to the action of said auxiliary heater, for the purpose specified.
